Install

Carthage

Add the following to your Cartfile:

github "multihash/SwiftMultihash"

Then, in the root of your project, type: carthage update --platform Mac

If you get the error 'Project "VarInt.xcodeproj" has no shared schemes'

Make sure your scheme is marked shared. For more details see here

• from the Multihash root type carthage build

You will then need to add frameworks to your own Xcode project:

• Select your target's Build Phases tab.

• Select the Link Binary With Libraries, click the + and then Add Other... buttons.

• Navigate to the Carthage/Build/Mac directory in your project root and select the SwiftMultihash.framework, SwiftBase58.framework and SwiftHex.framework.

• In case of a code signing error, select the target's Build Settings tab make sure the "Code Signing Identity" is either a valid identity or "Don't Code Sign".

For more information on how to install via Carthage see the README

Requirements

• Swift 3

Usage

import SwiftMultihash 
import SwiftHex

func test() {
    
    if let buffer = SwiftHex.decodeString("0beec7b5ea3f0fdbc95d0dd47f3c5bc275da8a33") {
        let (multihashBuffer,_) = SwiftMultihash.encodeName(buffer, "sha1")
        if let mhb = multihashBuffer {
            
            var multihashHex = SwiftHex.encodeToString(mhb)
            println("Hex: \(multihashHex)")
    
            let (object, _) = SwiftMultihash.decode(mhb)
            if let obj = object {
                
                multihashHex = SwiftHex.encodeToString(obj.digest)
                println(String(format: "obj: %@ 0x%X %d %@\n", obj.name!, obj.code, obj.length, multihashHex))
            }
        }
    }
}
